Sweden’s reindeer population is on the verge of extinction – because it’s too cold for them. The beasts – famous for their survival in Arctic conditions – have been struggling to find food on their mountainside habitats which are still covered in thick snow. “We’ve had bad years before but we are really worried how this will work out. “I’ve already started finding dead reindeer calves on the mountain,” said herder Mikael Jonsson from Rans Sami village.
